Adult webcam chat

Looking for a professional who can develop a live adult webcam and chat site very similar (but better) to webcams dot com Every feature has to closely match webcams dot com features. A special request is to include an option for the models that would sign up/register to enable or disable IP addresses/users located in their same country/city. This is specially for some girls from certain countries that would like to make money but cannot do it for fear of being seen by relatives. This is for privacy concern... option shall include at least block/unblock clients in their home country or city(town). Menu, design, cam window, assortment of options need to be quite similar to webcams dot com's. Needs to be easy to manage, easy site update and maintenance. I have no IT experience at all. Recommendations are very welcome. Website need to be user-friendly and nice interface to persuade potential clients to register.
